Case Study: Downsizing Close to Family

Location: Central Toronto (address withheld for privacy)

The Situation

A family living in central Toronto wanted to create a housing solution that would allow a widowed parent to live nearby while maintaining independence.

The homeowners were part of the “sandwich generation,” raising three children while also supporting an aging parent. Their property was well located with strong access to public transit, schools, and services. The lot itself was typical for the neighborhood but included a portion of the backyard that had become overgrown and underused.

The plan was to construct a detached garden suite in the rear yard that could serve as a comfortable private residence for the homeowner’s mother.

The mother spends several months each year travelling outside the province and wanted a smaller, more manageable home base in the city where she could store her belongings and stay when she returned.

The Site

Before construction, the rear portion of the yard contained:

overgrown vegetation
an aging shed
old children’s play equipment
underutilized outdoor space

The garden suite allowed the homeowners to repurpose this unused portion of the property while maintaining a functional family yard.

The Challenge

The primary technical challenge on this project related to fire protection requirements.

The proposed structure was located more than 90 meters from the nearest fire hydrant, which triggered additional fire protection considerations under the building code.

At the same time, modern building code requirements meant the unit also required a Heat Recovery Ventilator (HRV) system for fresh air exchange. HRVs require both intake and exhaust air connections.

When these ventilation requirements were combined with the fire protection rules, the result was an additional design constraint:

the ventilation system required fire dampers to ensure compliance with fire protection standards.

Finding the appropriate equipment and coordinating the installation required additional work, but the correct fire-rated dampers were ultimately sourced and installed, allowing the project to pass inspection.

Design and Construction

The garden suite was designed as a compact, fully independent residence including:

One bedroom
One bathroom
Full kitchen
Living space

The project proceeded smoothly once the technical requirements were addressed.

The total project cost was approximately $250,000.

The homeowner opted for a higher-quality exterior finish, which enhanced the visual integration of the new structure with the main house and surrounding neighborhood.

After the suite was installed, the homeowners also completed several outdoor improvements, including:

rebuilding the rear deck
installing new pavers and landscaping

These changes significantly improved the appearance and usability of the backyard.

Downsizing Challenges

One unexpected challenge emerged when the mother first moved in: downsizing from a large home into a smaller space.

Initially, she attempted to bring nearly everything from her previous house. The result was an overwhelming number of boxes that made it difficult to move through the space.

Over time, she was able to sort through belongings and adapt to the smaller footprint. Ultimately, the space proved to be a much better fit for her current lifestyle.

Financial Considerations

A major benefit of this arrangement was the ability for the mother to unlock the equity that had accumulated in her previous home.

Her original house was fully paid off, meaning a significant portion of her wealth was tied up in home equity. Without selling the property, the primary ways to access that capital would have been:

taking out a reverse mortgage, or
leaving the equity largely inaccessible.

By selling her primary residence and downsizing into the garden suite, she was able to free up a substantial amount of capital.

Only a relatively small portion of that equity—approximately 10% to 20% of the value of her former home—was needed to construct the garden suite.

This allowed her to convert a largely illiquid asset into accessible funds while still maintaining a place to live in the city. From a financial planning perspective, this also addressed the opportunity cost of having a large amount of capital tied up in a single property, particularly in an environment where housing prices may not experience the same rapid growth seen in previous decades.

Reduced Operating Costs

Another important financial benefit was the significant reduction in ongoing housing expenses.

Maintaining her previous home involved substantial fixed annual costs, including:

property taxes
utilities for a full-size house
ongoing maintenance and repairs
landscaping and general upkeep

As she grew older, the responsibility of maintaining a large house became less appealing.

By downsizing into a smaller approximately 500-square-foot garden suite, many of these costs were dramatically reduced. The smaller space requires:

lower heating and cooling costs
reduced maintenance
minimal upkeep compared with a full-size house

This transition removed many of the large fixed annual expenses associated with her previous property, making her housing costs simpler and more predictable in retirement.

The Outcome

The completed garden suite transformed an underused portion of the backyard into a comfortable and attractive living space.

The homeowner’s mother now has a private residence close to family while enjoying the freedom and flexibility that came with downsizing.

For the homeowners, the project created a multigenerational housing solution that works well for their family while significantly improving the usability and appearance of their backyard.

Key Takeaways

Garden suites can help aging parents downsize while remaining close to family.
Underused backyard space can often be converted into valuable living space.
Building code requirements such as fire protection and ventilation systems can introduce technical challenges that require careful coordination during design and construction.
Downsizing can unlock home equity and reduce ongoing housing costs, improving financial flexibility during retirement.
